I like ladybug's response to a totally stupid, ignorant comment like that. I personally would have said.....

" It's wonderful, where else can I drink my espresso coffee, kick back on my sofa, put my feet up and watch my soaps all day long whilst the kiddies quietly amuse themselves with books and puzzles". Then If I really have some time in the afternoon, I'll give myself a pedicure and rearrange my sock drawer." ....but then again, I tend to be a smart ass who will sling around a passive aggressive remark or two. But only when I'm really ticked off. That comment would have ticked me off. A lot.
